To cir/ZZ whom, t may concern:

Be it known that 1, DANIEL W. SMEDLEY, a citizen of the UnitedStatesrresiding at Wilmot, in the'county ofSt'ark andfState ofV Ohio,

have invented' certain newan'dius'eful Improvements in Vehicle-Axle Lubric'ators; and

sectionof the axle,showing the cup and "itsvalve properly arranged. Fig. 4 is an enl larged view showing` the end of the valvechamber and the stops. Fig;.5 is a detached View of the axle-nut. Fig. 6 is a view showing a portion of the axle and illustratinga portion of the hub-boxing located thereon and illustrating one of't'he lubricating-slots., Fig. 7 is a longitudinal section-of the cut-'oitl valve.

The pres-ent inventionjhas ,relation to Vvehicle-axle lubricators; anditconsists in the dierent parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar numerals of reference indicate cor-y responding partsin all the figures of the drawings. o

usual manner, reference being had to attaching my improved devices thereto. The end of the axle is provided withV the usual screwthreadedportion 2 yandzisalso provided with the iixed'collar 3, which iixed collar is provided. with the annularv groove 4, said groove being for the'purp'oserol:`- receiving and holding a washer 5,- which washer is formed of any suitable material, and the side thereof toward the collar is provided with a felt disk G, this arrangement being for the purpose of preventing a waste of oil.

For the purpose of preventing the oil from In the accompanying drawings, 1 .represents a portion of the axle, which is formedinthe escaping from the outer end of the'axle the Washer 7 is provided, and for thefp'urpose of vadjusting the nut 8, so as to properlyhold the boxing 9`ofthe hub, the adjustingscrew 10 is provided, .this arrangement -being important in this class of llubricators, as I am enabled tosov regulate .the adjustmentof the ,n ut 8 u-pon the vv-asl1er7` thatitwill be held in such a position that the oil cannot easily escape.

The axle 1 is provided with a groove, which groove is formed of such a depth thatthe oilconveying pipes 12 and 13 can be placed therein, one above the other, the lower one extendingIk to and communicating with lthe open slot I4 and the upper one communicating with the slot V15, and for the purpose of retaining the pipes in proper position and at the same time closing the groove said groove should be iilled with suitable metal after the pipes 12 and 13 Ahave been placed in proper relative position.

The pipes 12 and 13`are extended upward, as illustrated in Fig. `1,4 and communicate with the valve-chamberpldwhich valve-chamber contains the valve `1`,7, which valve is providedwith the oil-passage 18, the top or upper end of which passage i'sunneIshape, so that when the valve 17 is turned to bring the passage 18 in alinement With theproper pipe 12 orf 1'3.th`e communication will not be out o from-,thebil-pipe 19; but'when'it is desired to out off'the supply of oil the-valve 17 is turned so as to bring the passage 18 directly between the top or upper ends of the pipes 12 and 13,

'thereby cutting o the supply of oil and prevent the Waste of oil.

I AAbove Vthe valve-chamber is located the oil- 4cup 20p-'andi is formed of sufficient size to hold asupplyof oil for a considerable length of time. f

The to`p or upper end of the oil-cup 20 is provided with the screwthreaded -cap A 21, which screw-threaded cap is provided withan aperture to receive the stem 22, tothe top'or upper end of which is attached the knob 23. The stem 22 is screw-threaded below the cap 21, and on said screw-threaded portion is located the piston 24.

It will be understood that by turning the knob 23 in one direction the rotation of the stem 22 will move the piston downward and force the oil through the passage 1S and into IOO the proper pipe 12 01'13, reference being had to the position of the valve 17. It will be understood that by this arrangement I am enabled to force the oil through the pipes 12 and 13 and outward onto the axle through the slots 14 and 15, and by providing the screw-threaded stein 22 and placing the piston 24 thereon I am enabled to force heavy oils through the passages 19 1S and the pipes 13 and 12.

For the purpose of preventing the piston 24 from rotating during the time the stem 22 is rotated the inner periphery of the cup 2() is provided with the ribs 25, which ribs are located in the notches 26, formed in the piston 24.

For the purpose of preventing; the oil from passing the piston 24 a washer 27, formed of flexible material, is connected to the bottom or under side of the piston 24. This is done by suitable screws or in any other convenient and well-known manner.

For the purpose of stopping the valve 17 at the proper point to bring the passage 18 into proper alinement stop-pins 28 are provided, which stop-pins are located on the housing of the valve-chamber, as illustrated in Fig. 4, and the valve 17 provided with the pin 29.

For the purpose of throwing the bearing of the vehicle-hub proper at the inner and outer ends thereof the axle 1 is out ont, or, in other words, formed of less diameter, so as to produce the open space 30 between the hub-boxing 9 and the axle l.

For the purpose of leading the oil from the slots 14 and 15 the grooves 31 are provided, which grooves are formed upon portions of the periphery of the axle 1, preferably at the ends of the slots, as illustrated.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a vehicle-axle lubricator, an axle pred vided with a groove having located therein oil-conveying pipes, said pipes being covered with metal, and leading to and communicating with open slots,and the axle provided with a reduced portion between the bearing-points of the hub-boxing, and an oil-cup provided with a passage leading to the oil-conveying tubes, and means for forcing the oil through the conveying-tubes from the cup, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DANIEL W. SMEDLEY.
